We want to study the impact of a sledgehammer and a wall.
Before the sledgehammer hits the wall, it has a given velocity and a given mass, so it has momentum and it has kinetic energy.
When it hits the wall, the velocity of the hammer disappears, this means that the energy is transferred to the wall, this "transfer of energy" can be thought of a force applied for a really short time on the wall, which for the third law of Newton, the force is also applied on the hammer.
This is why you feel the impact on the handle when you hit something with a hammer, this also means that some of the energy is dissipated on your arms.
Now, because the wall is made of a material usually not as strong as the head of the sledgehammer, we will see that in this interaction the wall seems more affected than the hammer, but the forces that each one experiences are exactly equal in magnitude.

kess dense material comes up. glycerin dencity= 37.8 / 30
syrup density = 80 / 60 so glycerin is less dense and comes up
It is a completely false statement that to form a negative ion, an atom will <span>give up an electron to gain stability. The correct option among all the options that are given in the question is the second option. Negative ion has more electrons and so it would be wrong to say that it will give up an electron. I hope the answer has helped you.

Answer:
Explanation:
As we know that the energy stored in the capacitor is given as
here we know that
also we know that
now we have
now we know the formula of capacitance
I think the answer is D, but I’m not at all sure :l
